Change fails to save if FF breaks Rated 5 out of 5 stars

I like speed dial deeply. While, there is a bug. If some changes was made, then FF broke down. After restarting FF, I would find all the changes lost and everything went back.

Can you save the change in time before shutting down FF?
Thank you!
